Be it known thatfI; 'Townnn K. VVEB- strnn, Jr,- a citizen of the United States, residing at Eva'nston, i-n'the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Tanks for Ash-Conveyer Systems, of which the following is a'full. clear, concise; andexact description, reference being had to the accompanyingfdrawings; forming a part of thisspecification. I p v My invention relates to ash convey' er systems, and more specifically 'toash'tanks ar-. ranged to rece ve ashes froma conveyer for use in connection with a steam ash can veyer system which is efficient in its operation and which can be manufactured economically.

A further object of the present invention is the provision of apparatus for draining water from the contents of the tank so that the same readily may be discharged from the tank without sticking and clogging in the discharge gate or chute. Incidentally, the removal of the water from the tank contents prevents freezing during the winter months.

A further object of the invention is the provision of an arrangement for agitating the ashes contained within the tank to feed the ashes to the discharge gate located at the lower end of the tank.

These and other objects of the present invention will be pointed out more clearly in connection with the accompanying drawings, wherein,

Figure 1 is a vertical cross sectional view of the ash tank of my invention;

Fig. 2 is a top view of Fig. 1;

Fig. 3 is a horizontal sectional view taken along the line 3-3 of Fig. 1 looking in the direction indicated by the arrow;

Fig. 4: is an enlarged detail cross sectional view of the lower end of the tank showing the drain pipes and steam nozzle; and

Fig. 5 is a detail cross sectional view of the discharge gate employed at the lower end of the tank.

Similarcharajc'ters of reference refer to similar 1 parts throughout the several views.

- Referfingfirst'to Fig. 1, 6 designates a'suit- I 7 able support,'pr'eferably constructed of concreteg 'up'on'which is mounted-"an ash tank 7 substantially cylindrical in "shape and preferably- 'constructed of concrete. Leading into "theyuppe'r' endpf the tank 7 is an ash "conveyerconduit 83 which extends through deflector plate '9 car'riedb y the cover of the tank 10. Carried by the cover 10 'POSllLlOIlBCl opposite the discharge opening of the ash eonv yer conduit 8 is a bafiie plate 11 "against which the ashes delivered byytheco ve er conduit 8 are arrangedfto s i e. A'suitable ventis employed at 12 Located in the floor ofthe tank 7 and preferably centrally located with respect thereto is a discharge opening 14 provided with a gate 15. Mounted upon the floor of the tank and disposed around the discharge opening h is an annular steam nozzle pipe 16 provided with a plurality of openings 17-17 arranged to project steam into the tank. The annular steam nozzle pipe 16 communicates with a steam supply pipe 18 extending outwardly from the tank and leading to a suitable steam supply. The interior of the discharge opening pipe 14 also communicates with the steam supply pipe shown at 18 and is arranged to receive steam from the pipe for the purpose hereinafter pointed out. Carried upon the floor of the tank 7 and disposed around the steam nozzle 16 is a plurality of drain pipes 19-19 which communicate with one another, as shown at 2020 in Fig. 3, and lead to the atmosphere as shown at 21 in Fig. 4:. These drain pipes are 'made of porous material, and preferably constructed in sections, as illustrated. The end of the drain pipe 21 leading to the atmosphere is connected with the steam supply pipe 18 through a manually operable valve shown at 22.

The operation of the device is as follows: The ashes are conveyed from their source, which may be a boiler room or a locomotive ash pit, through the pipe 8 by means of steam. As the ashes are projected through the conveyer conduit 8 they strike the baflie plate 11 and fall downwardly to the lower end of the tank. Some of the steam escapes i 7 ,Because of the reaches'the drain pipes 19 it seeps through the porous -material"and" passes out of the tank through the end 21 of the drain pipe. WVhen it is desired to remove the ashes from thetank the gates 15 are opened and most opening. There is, however, a' certain amount of ashes leftwithin the tank, as shown in Fig. 1; Steam is then projected through the pipe 18 and through the open:

ings l7.17.in the annular pipe l6'against the remaining ashes with the resultthat the ashes'are removed to the extent shownby the dotted lines in F ig. 1.- Some of the steam projected through the nozzle passes through the vent opening 12 while the remainder condenses and escapes through the drain pipesl. provision of the drain pipes, the tank contents and more particularly the ashes adjacent the discharge chute are kept comparatively free e from moisture with the result that they flow freelyfrom the tank without sticking or clogging when the discharge gate is opened. vIn the'event Copies of this patent may be obtained for conduit 18.

of r freezing within the discharge pipe 14 steam is admitted through the steam supply In case the water freezes at the point of its discharge from the drain pipes '19 the valve shown at 22 is opened.

' Having thus described my invention what I claimas new and desire to secure by Letp 7 I ters Patent of the United States is; of the ashes within the tank 7 permitted to pass downwardly through the discharge LAirash conveyer system comprising an ash tank having a, substantially flat bottom provided with a discharge opening, means located adjacent the bottom ofisa'id tank for separatmg. water fromthe ashes deposited on the bottom of said tank, and means located adjacent said opening fordirecting steam jets upwardly and away from sald open ng. 1

. 2. An ash conveyer system comprising an ash tankhavingv a substantially flat bottom providedwith a vdischarge opening, and

means adjacentsaid discharge opening for projecting steam jets upwardly and away from said opening. r i I In witness whereof, I hereunto subscribe my name this 9th day of August, A. D. 1917.
